Easy to install and fill the batteries. Worth it. Will make life easy and faster and can make sure the batteries are full more often. Will agree with some of the others in that the bulb you need to fill the batteries should come in the kit. Remember if you have 4 batteries (as I do) you need 2 of these systems but only one bulb filler. Great product and well made.

Must have

I received the Pro-Fill a few weeks ago. I had a little problem installing the valves on the
two six volt batteries (they were in place and hard to reach) Once installed, I was VERY
happy with product. A few weeks ago I installed a solar charge system on my motorhome,
thus the need for proper water levels in my batteries. I think this product is a must have for
hard to access batteries. Takes no time at all to maintain proper levels.

Great Product

Despite being situated in a slide-out tray, gaining access
to check or add water to my batteries was very difficult. I
have 4 6-Volt batteries connected in a series/parallel
arrangement so it was necessary to purchase two kits in
order to connect to all the cells. Installation was fairly
simple and now adding water couldn't be simpler. I just
connect the filler bulb and hose via the quick-connect
fitting, drop the free end of the hose into a bottle of
distilled water, and squeeze the blub until it resists
further pumping. Not a drop of water spilled. Since it is so
simple, I confess I correct the water level MUCH more often
than I did prior to installing the system and I have been
surprised at how much water I need to add. I am a full-timer
so the batteries are always in use, either being discharged
or recharged. The only improvement I can identify would be
to incorporate some sort of release that would allow
residual water in the fill hose to drain back into the water
bottle once the filling process is complete. I highly
recommend this product even if battery access is already
very good.

upon recieving the Pro-fill water system I was amazed at how simple it was to install.
Removed battery fill caps,, put away for emergency. I then installed the pro-fill system, in less than a couple of minutes. Now I do not have to get a mirror in one hand and try to fill the batteries with the other one and trying not to over fill the system. This system is worth its weight in gold.

You need Pro-Fill

Before Pre-Fill, I had real difficulty filling my house batteries properly because I could not see the water in the cells due to height restrictions. With the system, all I have to do is put the tube with the bulb on it into the distilled water, squeeze the bulb until the tube is filled, attach the tube to the tube extending from the batteries using the attached coupling, then squeeze the bulb until high resistance is encountered. The batteries are no properly filled.

I installed a set of these 5 years ago to make the process much easier to fill my house
batteries. Without this filler unit, I would have to disconnect all house batteries and
remove them from the pull-out tray. With the auto-fill, you simply connect to the first
manifold and allow distilled water to siphon out of the water container. When it is full and
just starts to over flow, I stop and wash off the spill with plenty of tap water.

Easy,Easy, Easy!

I have had this in our motorhome for over a year. No problems at all. I have used it numerous times as we live in the Mojave Desert and have not had the ball failure problem. We just put in 2 new Golf Cart batteries and the new batteries had a shorter distance between caps. This was remedied very easly by using the second set of caps and just shorting the distance. Took about half an hour and saved the price of a new unit. I recommend the Pro-Fill for any batteries that are hard to reach as mine are. It used to take 2 or 3 times the the amount of time to re-fill. Now it's a simple and easy 5 minute job.

Needs some redesign of the pump tube materials

I like this product although the pump failed in a short time due to the "ball stop" back-flow preventor rusted or corroded and froze up up after short use. I have to get a new one to use the filler properly. I was
disappointed in the resilience of this. It should be constructed of material that can stand water dampness being left in the pump tube as there is no way to dry it out. Very disappointed in this feature.

6-volt system easy install

I bought two of these to install on 4 six volt golf cart batteries. They slip right in to the top and lock in place. I was able to tie both systems together. (The manufacturer suggests a limit of 6 batteries per system.) Very easy install. I bought these because my battery compartment has less than one inch clearance on top of the batteries, and there would be no other way to add water! To add
water, you just hook up the bulb (bought separately) and squeeze it until it won't squeeze anymore. Presto, the batteries have the right amount of water!

Saves me a lot of time

I retrofitted my 5th wheel with 6 volt golf cart batteries
which have next to no clearance in the battery compartment
due to their increased height. Without this system I would
have to unhook and wrestle the batteries out of the
compartment to check and fill them each time. With this
system in place , I just slide the fill bulb onto the unit
and pump it. When the battery is filled the float valve
cuts it off so it doesn't get over filled. The price is a
little outrageous as it probably cost the company 3 dollars
in parts to manufacture but worth it to me given the hassle.

THE PRO-FILL SYSTEM IS JUST WAY TOO COOL!!!

I received my remote battery fill system yesterday with much
anticipation. I had it installed in about 10 minutes and
pumping the Pro-Fill Handy Pump and kind of chuckling all
the while. The best way to describe the system…its way too
cool. Where my batteries are located I would have to remove
the caps, shine a light and try to see the water level in
each cell. Of course I had to add water and that was another
trick. I really did not like the task but one that had to be
done. Now with this system it is so quick, easy and fool
proof. Well worth the price! I really recommend this to
anyone that has to fill batteries.

Like my wife... expensive but worth it

I had to buy two sets for the 4 house batteries I have in my coach and then the extra 17 bucks or so for the filling attachment. Too expensive for the cost of materials involved but priceless for the convenience of the system because it really works well.

The Pro Fill System Is Great!!!

I have had this system on my 5th wheel for over 2 years. I have 2 6 volt Interststes. They were hard to see and hard to fill to the proper level before I got this system. Now they are not over filled and can be filled with out even pullling the batteries out. It takes longer to set up the simple system than it does to fill the batteries. With 2-3 squirts on the bulb and it is done for another month. Total time to set up and fill is about 5 mins. or less. I sold my 5th last week, and that system helped me close the deal. So from now on I will not be without them on my next 5th and on my new golf cart which has 6 batteries.

Installed a Pro-Fill system on my RV. Much easier to fill batteries but "Discription" should state that Pro-Fill™ Handy Pump is REQUIRED to use the Pro-Fill RV Edition Dual 6-volt battery system. Other wise, VERY easy to install and use!!

Excellent Watering System

I have an older 5th wheel with two 6-volt batteries. To remove the batteries to check them requires first disconnecting them by reaching you arm back into the compartment and disconnecting the cables on all fours posts then removing the batteries from the compartment with about 1/8" clearence on each side, checking the water levels and then wedging them back in and reconnecting the cables. After installing this sytem all I have to do is "fill" them each month. No more busted knuckles, no more battery acid on my arms and no more chance of electrical shock. Great product that is saves time and insures good battery maintenance.

The Pro Fill system is everything it's said to be. Installed on a Class A motor home and only took about 15 minutes. I lost 4 batteries due to watering negligence. Never again with Pro Fill. And you don't need to pull out those heavy, rusty trays. Now I know my inverter system is running properly because the batteries have enough water!

What a Great Product..!!

I got this directly from Pro-Fill about 4 months ago - 2 sets for 4-6volt batteries. What a great product..!! Remember how messy and inconvenient filling batteries is with the hygrometer (or perhaps you don't use a hygrometer and do it by the old drip method from the water container). Remember overfililng and having the electrolyte boil-off during charging, creating a HUGE mess..??!!!
NO MORE - with Pro-Fill, you just insert the pick-up tube into the Distilled Water container and pump until it doesn't pump any more. That's it.. DONE..

Great product!

We installed a Pro-Fill on the coach batteries of our class C. Installation took only a few minutes. The system is easy and convenient to use - both plusses that will help you better maintain your batteries. Just a little quick pumping with the filler every month or so keeps the electrolyte at the proper level without overfilling.
Make sure to get the filler device as well.
